AUTOMATIC PROGRAMMING TIMING WAVEFORM

One byte data is programmed. Verify in fast algorithm and

additional programming by external control are not required

because these operations are executed automatically by

internal control circuit. Programming completion can be

verified by DATA polling and toggle bit checking after

automatic verification starts. Device outputs DATA during

programming and DATA after programming on Q7.(Q6 is

for toggle bit; see toggle bit, DATA polling, timing waveform)
